The Vacuum Group A Vacuum Physics Group of the IOP was inaugurated in 1965 and its success in arranging meetings involving many disciplines besides phys- ics led to the amendment of the name of the Group to 'The Vacuum Group'. The Group continues its endeavours to represent those in the vacuum community and to appeal to as many as possible in academe, research and industry by arranging meetings covering the widest possible range of subjects. To this end the composition of the Group Committee reflects the broad coverage of the subjects aimed at by the Group, encompass- ing academics, representatives of vacuum manufacturers and vacuum users in government and industrial laboratories. The Group has been successful in bringing together those engaged in the production and im- provement of vacuum equipment with those concerned with its applica- tion in such diverse areas as medical physics, large machines for re- search in the physical sciences, industrial process control and the elec- tronics and semiconductor industries. The Vacuum Group has approximately 600 members with 20% being outside the UK and Ireland. 35% are in the 18-24 age group range which bodes well for the future of the group! The Group aims to organise a programme of half-day and full-day meet- ings, some of which have taken the form of workshops and included 2 VACUUM Group newsletter 2020 mini-exhibitions. The group has also actively participated in the Vacuum Symposium UK series of conferences. The Vacuum Group takes an active interest in education for those work- ing with vacuum technology. The Group maintains close links with the British Vacuum Council (BVC), the International Union for Vacuum Sci- ence Technique and Applications (IUVSTA) and Vacuum Symposium UK. 2. Report of the Chair 2019-2020 It is a pleasure to write for the first time as Chair of the Vacuum Group. I took over from Dr Ron Reid at the start of October 2019 for a four-year term and I would like to thank Ron for all his hard work and stewardship of the group during his term of office. During 2019 Group activities included the “Vacuum through the years” meeting as well as 3 other joint-meetings: details are later in the newsletter. The committee membership has had a significant turnover in the last 18 months and I would like to thank the previous members of their work and contributions to the group. I write this report during the Covid-19 pandemic which has clearly impacted significantly on the 2020 plans for the group and the entire Global Vacuum Community. Unfortunately, this means the planned 2020 Training Course has been cancelled until 2021. As I write (August) the Vacuum Symposium VS11 has been cancelled, as has the American Vacuum Symposium originally scheduled for October. The group continues to operate with remote committee meeting calls and making plans for events in 2021. I hope you find the Newsletter of interest and I welcome any comments regarding this and the Vacuum Group as a whole. Andrew Chew, August 2020 3 VACUUM Group newsletter 2020 3.

Report on 10th Vacuum Symposium 9-10th October 2019, Coventry, UK https://www.vacuum-uk.org/ The 10th Vacuum Symposium UK was held at The Ricoh Arena in Coventry on the 9th and 10th October 2019. Several Symposia were held including Vacuum Through the Years which sought to encompass vacuum progress over the years with a focus on major milestones. The meeting was sponsored by the Institute of Physics Vacuum Group. Dr Sunil Patel of STFC Rutherford Appleton Laboratory and Dr Andrew Chew of Atlas Copco Scientific Vacuum Division chaired the meeting. Speakers presented historical progress from a wide range of vacuum technologies. Mike Thompson of Edwards gave a highly illuminating talk on the History of dry pump applications in semiconductor processing which charted the evolution of application challenges and customer requirements on vacuum pumps from the 1980s. The development and introduction of dry pumping and successive generations were discussed relevant to drivers of larger wafers (and gas flows), the reduction of power and pump size. Future trends included a discussion of the 4 VACUUM Group newsletter 2020 continual introduction of new materials with associated new precursor and by-product challenges. 60+ years of ion pumps from invention to latest developments was presented by Mauro Audi of Agilent Technologies and chartered the history of ion getter pumps and their applications over the decades; the reduction in required power being especially highlighted. The latest developments were discussed including a new combination of magnetic field and cell dimensions to produce the first ion pump with pumping speed maximised in the low pressure range; minimization of charged particle emissions and a combination with NEG pumps. Enrico Maccallini of SAES Getters presented Non Evaporable Getters: evolution and experience of more than 40 years. He discussed how NEG pumps have been developed since the 1970s and their adoption across industry, R&D laboratories and accelerators, with a special emphasis on the capability to -pump hydrogen. Recent developments in ZAO® alloy were shown with the benefit of extending to the high vacuum pressure range Kris Haran of Pfeiffer Vacuum presented Dry versus wet pumps – different dry pump principles. The development of dry pumps having not reduced the ongoing popularity and application of OSRV wet pumps. The meeting was finished with a presentation by Jonty Bray of MKS Instruments who discussed the fascinating historical development of gauging over the last four centuries. The technologies and characters who developed them and the drivers for new gauging was greatly appreciated by the audience. A poster session was held during the lunch interval and the Harry Leck Memorial Medal for 2019 was presented to Dr Alan Webb for his significant contribution and understanding of plasma chemistry, plasma physics and thin films in both business and academic positions. Other meetings included the Structure and Dynamics of Surfaces and Interfaces (with the BVC 60th anniversary presentation from 2019 IUVSTA Prize for Science winner Prof Phil Woodruff); Thin Films and Coating Technologies for Science and Industry; 17th Technology Plasma Workshop and Surface Analysis- The Changing Composition at the Surface. Seven Vacuum Technology Training Courses were run for newcomers to the field as well as those wishing to expand their knowledge further 5 VACUUM Group newsletter 2020 into UHV and techniques such as Leak Detection and Residual Gas Analysis. The aim of these courses is to lay the foundation for a more advanced course organised by the Vacuum Group on Vacuum System Design and Maintenance originally scheduled for June 2020 (this has since been cancelled). The symposium was co-located with VacuumExpo https://vacuum- expo.com/. Nearly 40 companies exhibited from across the industry of vacuum techniques, products and applications. Andrew Chew 2019 Vacuum Group Poster Prize The winner of the 2019 IOP Vacuum Group Poster prize for posters pre- sented at VS10 was Ihar Razanau of Laboratory of physical-chemical technologies Scientific-Practical Materials Research Centre of NAS of Belarus, Minsk, Belarus. The poster title was “Surface hardening of seal- ing elements made of elastomers using coatings on the base of dia- mond-like carbon”. 6 VACUUM Group newsletter 2020 The Harry Leck Memorial Medal 2019 Each year the organising committee of Vacuum Symposium UK seeks nominations for the Harry Leck Memorial Medal. The Medal is awarded for distinguished contributions to British scientific research and/or related scientific/technical communities, in the field of Vacuum Science and Technology. The medal has been established to honour the memory of Professor John Henry Leck, known to his friends as ‘Harry’. Harry was a former Chair of the IoP Vacuum Group. 7 VACUUM Group newsletter 2020 The winner of the 2019 Harry Leck Memorial Medal is Dr Alan Webb, Consultant. Vacuum Symposium 2020 COVID-19 Announcement The organising committee of Vacuum Symposium UK have been monitoring the current and on-going situation regarding COVID-19, along with government guidelines. In view of the seriousness and uncertainty around this deadly virus we have decided to postpone VS11 until 2021. This was a difficult decision to take, but we had to consider the duty of care that we have along with the health and wellbeing of the VS family and all our supporters.

  • Fernand HOLWECK, Né Le 21 Juillet 1890, À Paris, Et Mort, À Paris, En
    Fernand HOLWECK, né le 21 juillet 1890, à Paris, et mort, à Paris, en décembre 1941, assassiné par la Gestapo en raison de ses activités de résistance, était un universitaire et un physicien-chercheur réputé dans le domaine des rayons X. Fernand Holweck était le fils d’un sculpteur parisien issu d’une famille alsacienne et catholique émigrée en France. Habitant le 14e arrondissement, il a fréquenté l’école Lavoisier puis, dès 1907, l’École de physique et de chimie industrielles de la Ville de Paris dont il est sorti major de sa promotion, en 1910. Fernand Holweck s’était marié en 1923 avec Jacqueline, une jeune femme d’origine corse. Ils eurent un fils, Jacques, et deux filles, Mireille et Gabou (sans doute un surnom). Holweck était entré à au Laboratoire Curie de l’Institut du Radium, dirigé par Marie Curie, en 1912, à 22 ans, comme préparateur particulier de la directrice du laboratoire puis assistant. Il était ensuite devenu chef de travaux, maître de conférences, maître de recherches et enfin, un grade alors rarement attribué, directeur de recherches au CNRS. Il y devint rapidement un spécialiste de l’étude des radiations existant dans l’ultra-violet lointain et des rayons X, dont il apprit à fournir des doses connues en intensité et en longueur d’onde. Ses travaux lui permirent d’obtenir le titre de docteur ès sciences à la faculté des sciences de Paris, en 1923. Ses recherches le conduisirent aussi à travailler constamment sur la réalisation de vides de plus en plus poussés, à étudier les effets biologiques des rayons X et à contribuer au développement de la radiologie.

  • Savants Français Dans La Guerre Mondiale 1914-1918
    Osmanlı Bilimi Araştırmaları XIX, ‘Savaş ve Bilim’ Özel Sayısı (2018): 21-44 Araştırma makalesi / Research article SAVANTS FRANÇAIS DANS LA GUERRE MONDIALE 1914-1918 FRENCH SCIENTISTS IN THE WORLD WAR 1914-19181 Denis Beaudouin & Dominique Bernard Abstract Many events and commemorative ceremonies have been organised in remembrance of the First World War. In this context, we present the activities of French scientists and scientific institutions during the period. We focus on the creation in 1887 of the “commission d’examen des inventions intéressant l’armée” and the contribution of the mathematician Paul Painlevé; the activities of some scientists contributing to the “war effort” despite their internationalist convictions: Aimé Cotton, Weiss, de Gramont and Chrétien, Langevin, Perrin, Marie Curie and Regaud; innovative research and development on scientific instruments in various disciplines, such as communications and radiotelegraphy, optics, chemistry, medicine and their applications; the contributions of the « grandes écoles parisiennes », for instance, the School of Industrial Physics and Chemistry; the impact of the WWI on the organisation of the French research and the creation of new research institutions, and the consequences of the loss of numerous young scientists. Key words: World War I, French scientists, inventions, French army.
